In the last episode, Jacob handed the MiB the bottle of wine to
pass the time. Earlier in a discussion with Richard, Jacob had
talked about how the cork kept the bottle closed and that the
island was like a cork. Instead of taking off the cork, the MiB
destroyed the whole bottle by smashing it on the log. Protecting
the cork will do little good if the bottle has been broken, so is
it possible that the MiB is not lying when he says the island
doesn't need protection, it's everything else that does.

Long time reader, first time poster and I'm not sure if this has
been discussed before. We know from Hawking that the island is
always moving. So, there are only a couple of possible scenarios
that would allow the losties to move through time while staying in
the exact same spot on the island. 1. While the island is always
moving, each of the time flashes send the losties to a historical
period in which the island has occupied the same exact geographical
position. 2. The time flashes create a worm hole to transport the
losties to the exact same spot on the island in a different
geographical location. 3. It was a simple oversight and we should
enjoy the time travel without thinking of the geographical
travel.
